Answer:
x = -7
Step-by-step explanation:
Eleven more than five times a number is equal to the difference between −38 and twice the number.
let x represent the number.
11 + 5x = -38 - 2x
7x +11 = -38.............add 2x to both sides
7x = -49................... subtract 11 from both sides
x = -7........................divide both sides by 7
Answer:
32 daffodils bulbs and 28 crocus bulbs
Step-by-step explanation:
Assuming 'x' as Crocus and 'y' as daffodil. Now we'll form equations.
-> for 60 small flowering bulbs
x+y=60
x=60-y --->eq(1)
->Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.65 each with the budget $27.80
0.25x + 0.65y = 27.80 -->eq(2)
Next is to substitute x=60-y in eq(2)
(2)=>0.25(60-y) + 0.65y = 27.80
15 - 0.25y + 0.65y = 27.80
0.4y = 12.8
y = 12.8/ 0.4
y= 32 daffodil bulbs
Now, plugging the value of y in eq(1)
(1)=>x=60-32
x= 28
x=28 crocus bulbs
Therefore, you can buy 32 daffodils bulbs and 28 crocus bulbs
X=0.5y+4;
5(0.5y+4) -3y =19;
Y=2, x=5
Answer:
3
Step-by-step explanation:
(x₁ , y₁) = (-1 , -2) & (x₂ , y₂) = (3 , 10)
![= \frac{10-[-2]}{3-[-1]}\\\\=\frac{10+2}{3+1}\\\\=\frac{12}{4}\\\\=4](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B10-%5B-2%5D%7D%7B3-%5B-1%5D%7D%5C%5C%5C%5C%3D%5Cfrac%7B10%2B2%7D%7B3%2B1%7D%5C%5C%5C%5C%3D%5Cfrac%7B12%7D%7B4%7D%5C%5C%5C%5C%3D4)
m = 4
y - y₁ = m (x - x₁)
y - [-2] = 4(x - [-1])
y + 2 = 4(x + 1)
y + 2 = 4x + 4
y = 4x + 4 - 2
y = 4x + 2
They can NOT. A right angle is 90°. An obtuse angle is greater than 90°. All the angles in a triangle must add up to exactly 180°. If two angles are greater than 90° then they will add up to greater than 180, beacuse 90 plus 90 equals 180. You cannot have a triangle with two obtuse angles because they will add up to greater than 180°.
